I've decided to try and take a stab at the camera bug bug, as described in issue 39975. As Angustmeta described, the problem is that the bug can not be reproducted on a private server.

My suspicion is that the bug is caused by the configuration. However, since I don't know how your servers are configured, I can't test my hypothesis. Is there somewhere where I could look up how your servers are configured, so that I could try and reproduce the bug?

When you activate the camera bug, you get a list of cameras, each with a "monitor" button to the right of it. Clicking the monitor button gives you a list of mobs visible from the camera (such as Sergeant-at-Armsky in armory). You can then click a "track" button next to a mob's name and you'll get a "Last seen near "Armory - Internal (now)"" text, where "Armory - Internal" is clickable to make you see from that camera.

It seems clunky and buggy on private server now. Clicking cameras sometimes has long delays, and when clicking the tracked person's camera you only get a few seconds of view before being kicked out.

Anyhow I think the camera bug item works now. At least I could click it as an observer on Terry today and get the list of cameras up.

The bug has gone through a few iterations but has never been used much due to its first, I think, version. Basically it was cheap but you physically had to go plant it into cameras so its use was kind of little in regards to remotely viewing something useful and you don't got access to.

Later on, after actual bugs regarding the item made it even rarer used, it got changed, and someone just made it hack the camera network. You can Still plant it, I believe, and wiki says it just lets you disable that camera now. It's been this way now for a good while. The camera picking UI menu runs like complete ass but nobody has ever commonly used this item afaik and I've literally never noticed anyone but myself even bother experimenting with them. (They're fucking good for 1 tc btw)

It might have been round 103191 (item worked) and 103201 (did not work). Both on Metastation.

But I can't remember for my life, and I recall seeing pda-bombs on the one where it didn't work which was not bought on any of those rounds in the logs, so I'm very disappointed in myself for not screencapping.
